When Good Traders Go Bad

Today's bad decisions can become tomorrow's legal disasters. Here's how to recognize the pattern of a trader about to go rogue.

Media coverage would have us believe that detrimental activity in the capital markets-including criminal behavior-is limited to individuals who are “different” from us. Many of us, as onlookers, believe that illicit, unethical or illegal acts are beyond us, that we would absolutely behave differently were we in the shoes of those we hear and read about.

Thanks to the concept of risk and return decision-making, we are not as quick to accept that conclusion.

Critics are quick to vilify (as they should) individuals and managements engaged in questionable and illegal market activities. Bernie Madoff, SAC, JPMorgan Chase’s London Whale and the Libor scandal provide ready examples. The fascinating thing about these “over-the-top” activities is that they are almost always grounded in the same fundamental decision-making practices Wall Street professionals use every day-at least at the outset.

Professionals make decisions every day. Some yield favorable results, while others turn out unfavorably. Unfavorable results are acceptable and expected. These routine decisions, individually, usually do not have a material impact on ongoing business. Some decisions may be questionable or inappropriate, but as the cautionary tales above illustrate, the payoffs can be greater than for routine decisions. Therein lies the temptation. No trader sets out to fail, let alone be fitted for handcuffs.

RISK AND RETURN IN DECISION-MAKING

The concepts of risk and return are familiar to everyone in capital markets. While they have obvious and direct implications in investment management and trading, so called “risk-based decision-making” can be a formal, defined, conceptual process, or one that is hardly noticed. In most cases, it depends on the perceived magnitude of the matter at hand.

In its most basic form, risk-based decision-making involves two factors: potential gravity (acuteness of the decision) and outcome probability (probability associated with favorable or unfavorable outcomes).

There is a wealth of academic research on these matters, and behavioral finance and economics are becoming increasingly important. However, it is clear that risk-weighting decisions in a logical and methodical manner will help clarify the impacts of a range of potential outcomes. And that knowledge helps a decision maker take optimal action.

DECISIONS IN A PRESSURE COOKER

Most industry professionals do not set out to defraud clients or create systemic events that will destroy their company. On the contrary, they spend years, if not decades, establishing reputations, demonstrating their abilities and building successful careers. The leap from bad decision-making to recklessness and illegality can occur subtly. It could start as simply as a bad split-second calculation made under stress. A trader may pursue an excessively risky proprietary trading position outside normal limits in an organization with a weak control structure. A successful trader may make the mistake of overestimating his or her capabilities or underestimating the market forces arrayed on the other side. A portfolio manager might impulsively act on nonpublic material information.

These decisions appear low-risk to the transgressor at the time because the potential upside is far more tangible than the seemingly remote-but very real-likelihood of loss or punishment. Once a step over the line has been taken, and the rewards tasted, the prospect of continued success often propels further action. Gains act like an addiction, compelling the transgressor to accept the delusion that the questionable activity is risk-free. When the losses inevitably come, they instill a sense of desperation to “get flat” before the inappropriate actions are found out.

In the context of risk-based decision-making, the transgressor overweights the immediate and visible upside against the more remote and, to his or her thinking, “almost nonexistent” downside. In their frenzy to claim credit for the unexpected-and undeserved-success, transgressors may not even recognize the downside as a possibility.

A pair of such decision makers in different realms of finance illustrate the point: Madoff and the J.P. Morgan London Whale.

For many years, Bernie Madoff ran a securities business which by all accounts was legitimate and prosperous. Bernard L. Madoff Securities began as a market maker for pink sheet securities and later grew to become the largest market maker on the Nasdaq. His infamous investment advisory business began in the early 1970s using low-risk arbitrage strategies surrounding his market-making business. After the crash of 1987, unsettled clients pulled substantial investment capital, forcing Madoff to unwind hedges on unfavorable terms. Madoff then developed an index options strategy that required market volatility to work, but markets at the time were flat. According to Madoff, he “borrowed” client capital as a stopgap to perpetuate his consistently high previous returns and keep his business going. That unexpectedly resulted in a huge influx of new investor capital.

To keep up appearances, and because the high profiles of his new investors “fed his ego,” Madoff continued the Ponzi scheme that resulted in his downfall. Once his scam was established, he deluded himself into seeing only the tangible aspects of wealth, materialism and inflated ego, all the while ignoring the downside of shame, punishment and prison that awaited.

In April and May 2012, J.P. Morgan’s Chief Investment Office incurred large trading losses based on transactions booked through its London branch by Bruno Iksil, the “London Whale.” A series of outsize derivative transactions involving CDSs were entered into, allegedly as part of the bank’s hedging strategy. The bank announced a $2 billion loss with expectations the figure would significantly increase.

Iksil made huge bets on thinly traded indices that caused irregularities in value versus market expectations. The positions stood to benefit if the credit markets improved or stayed the same. Not only were the bets bad, but given the relative illiquidity of the indices, it soon became clear who was trading in what direction.

J.P. Morgan head Jamie Dimon attributed the loss to “egregious mistakes” in trading. He called the strategy “flawed, complex, poorly reviewed, poorly executed and poorly monitored.”

We, like many others, doubt the Whale’s bets were made in the true spirit of hedging. It appears Iksil suffered the sin of hubris, vastly overestimating his ability to succeed and underestimating the potential downside to the bank. While not criminal, his activities resulted in embarrassing losses for J.P. Morgan. That ego drove a colored and faulty view of his strategy is illustrated by the fact that Iksil and his team were literally able to “shout down” and bully the relatively inexperienced risk manager overseeing the group’s activities.

THE FATEFUL DECISION

Thus we see that decisions to break the law, or less severely “step over the line,” are simply extensions of the same decision-making that occurs in the normal course of business. Individuals weigh risks and returns. Time, pressure and desperation may cause transgressors to leap from the relatively benign blue boxes to the more serious red boxes. Once in the red, the “candy” of the gain (or desperation associated with a loss) can be tangible and overwhelming. This is often sufficient to permit continuation of the questionable or illegal activity.

Acting in one’s own interest in the role of a fiduciary offers examples of fertile ground for questionable decisions. There is considerable legal ambiguity regarding fiduciary responsibility. It is therefore possible for a fiduciary to make some decisions in their best interests while not specifically breaking a law. Misuse of soft dollars is an illustration.

There are also decisions that have ramifications of criminal or civil liability. Insider trading is a clear example. One chooses-at the risk of fines and civil or criminal action-to trade on nonpublic proprietary information for virtually certain gain.

Decision-making consciously or unconsciously is a risk-based process. The temptation to step into the realm of the “inappropriate,” unethical or illegal is arguably within all of us. In most cases, the individuals don’t set out to be rule-breakers. They are confronted by situations in which they may be under pressure, may not have the time or focus, or may delude themselves into believing a legal transgression is not really a “line in the sand.” Once the transgression has been made, the pull from the immediate benefits, and lack of immediate negative implications, can incite continued behavior in the same vein. That’s when the risks overwhelm the rewards, and lives are ruined.
